IMPROVEMENT lN MACHINES FOR FORMING CHEESE-BOXES.

Specification forming part of Letters Patent No. I 75,977, dated April11, 1876 application filed March 10, 1876.

To all whom it may concern Be it known that I, ORRIN O. HARRIS, ofNewport, in the county of Herkimer and State of New York, have inventedcertain new and useful Improvements in Machines for FormingCheese-Boxes, of which the following is a specification:

The nature of my invention consists in the construction and arrangementof a machine for forming cheese or other hoop boxes, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a perspective view of my boxforming machine. Fig. 2 is across-section of the same, and Fig.3 shows the mechanism for expandingthe cylinder.

A represents the frame of my machine, constructed in any suitable mannerto contain the various working parts, as hereinafter described. Insuitable bearings on the frame A. is placed a horizontal shaft, B, whichcarries the rotating cylinder. This cylinder is made in two parts, eachpart consisting of headpieces connected by slats, as shown. Thehead-pieces of the part D are made enlarged in the center, so as to besecured on the shaft B, while the headpieccs of the part D arecorrespondingly cut out in the center. The two parts D D are hingedtogether at the point a, and along this joint to the part D is securedan inclined plate, 0, which laps over onto the part D. At the other endboth parts are provided with metal plates E, having projecting tonguesor fingers b b, which mesh with each other, as shown in Fig. 1. Throughthis end of the main part D of the cylinder is passed a rocking shaft,01, provided onits outer end with a crank, G, and within the cylinderwith two projecting arms, f f, between the outer ends of which isswiveled a nut, e.

Through this nut is passed a screw, h, which is swiveled in a collar,1', on a rocking shaft, d, in the part D of the cylinder. Above thecylinder is a tack-box, H, pivoted to standards I, and having a metalbar, J, at its front end to bear on the cylinder, the pressure beingcaused -by a spring, K.- arranged on the back of the box. The crank G ofthe shaft (1, being turned to the left, contracts the cylinder, which isthen turned to bring the plate G immediately in front of thepressure-bar J. The end of the hoop from which the box is to be made isthen inserted under the edge of said plate. By now turning the crank Gto the right the cylinder is expanded by bringing the arms f and bolt hin the same plane, and when the crank comes in contact with a stop, at,on the cylinder, this will commence to turn, the

end of the hoop being clamped by the plate (J, when the cylinder isexpanded. As the cylinder revolves, the pressure-bar J bends the hoopclosely around the cylinder, and when it has made a little over onerevolution, or when the ends of the hoop overlap each other, they aretacked together. The crank is now turned to the left, which collapsesthe cylinder, and by turning the cylinder a little to the left a pin,on, projecting from its inner end, will catch on a hooked arm, L,depending from the tackbox, and raise said box and pressure-bar up fromthe cylinder, when the completed hoop or box can be slipped 011' fromthe cylinder.

On the outer end of the part I) of the eylinder is a book, 19, to takeinto a ratchet, s, on the part D, to hold the cylinder expanded. Theextent of this expansion is regulated by turning the bolt h, so thatboxes of various sizes may be formed on the same cylinders.

R R represent adjustable guides placed in front of the cylinder, forholding the bands that are to encircle the box when made.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The collapsible cylinder, made in two parts, D D, hinged together,and provided at the joint with the clamping-plate G, and at the outerends with the plates E E, having intermeshing tongues or fingers b,substan tially as herein set forth.

2. The combination, with the bisected collapsible cylinder D D, of therocking shaft (1, with crank Gr, arms f f, and swiveled nut e, and therocking shaft 01, with swiveled bolt h,

substantially ,as and for the purposes herein In testimony that I claimthe foregoing as set forth. my own I affix my signature in presence oftwo 3.

4. The combination of the pivoted tack-box Witnesses: H with pendenthooked arm L, and the pin JOHN G. BARRY, m in the end of the cylinder,for the purposes MILLARD N. PEARCE. herein set forth.
